Going from 5 to 6..

[Redorangeyellowgreenblue]

Is there much difference going from 5 to 6 Kids?

Probably not when they are younger. I think the cost you need to think about is when they are teenagers though.
Small children are relatively cheap apart from childcare. Do you have a car that can accommodate you all - I had a friend who went from 4-5 and this caused their biggest issue.

I don’t have many children myself but I am from a large family from an area/time when large families were common. We all had little money as teenagers especially.
My friend of 5 now has 5 teenagers/preteens now finds it hard. It was fairly easy when they were younger but she has 5 children who eat more, need more expensive clothes and worst of all - have activities they need to be taken to! They also need more individual attention as they are all very different now.
